In heterogeneous catalytic processes the Arrhenius parameters are often found to be interrelated (compensation phenomenon). Using state-of-the-art experiments and density functional theory, the origin of compensation is studied. A similar dependence on the rate-limiting surface-coverage term is found for both apparent activation energy and prefactor terms, which can be translated into surface configurational entropy contributions.
